Large prawns (peeled and deveined), onions, and a squeeze of Calamansi lime juice to add a tangy zest.
A blend of fresh red chilies, onions, garlic, and shrimp paste forms the base for the sambal, adding depth, heat, and umami to the dish.
For a vegetarian-friendly version, substitute the prawns with firm tofu, hard-boiled eggs, or a mix of vegetables like okra, long beans, eggplants, or petai for a delightful twist.
